NOTICE!• These materials are prepared only for the students enrolled in

the course Distributed Software Development (DSD) at the

Department of Computer Science and Engineering,

University of Mälardalen, Västerås, Sweden and at the Faculty

of Electrical Engineering and Computing, University of Zagreb,

Croatia (year 2013/2014).

• For all other purposes, authors’ written permission is needed!

• The purpose of these materials is to help students in better

understanding of lectures in DSD and not their replacement!

Please talk about Rafael leaving the team here

Marin Orlić

Mention the project roles

Outline

Requirements

Design

Project plan

Project Status

Marin Orlić

There's no need for this much detail in an outline, keep this for internal use but for presetnation make a shorter version with just a few points and do not waste much time on this during presentation

System Goal

Marin Orlić

The text here might be unreadable. Last time you had text in the architecture diagram, only the top 2 levels of text were readable in Zagreb

**

Use Case Models

Marin Orlić

Text could be too small

Marin Orlić

Figure overlaps title (this is next phase, i know .)

Functional Requirements 1/2

Manager Web App Driver

• Viewing user’s schema;

• Selecting RDF endpoints;

• Creating relations;• Editing schema and

particular relations.

• Client App - Server App connect through JDBC postgres driver;

• PostgreSQL for transfering the query and result;

• Query parsing.

Marin Orlić

Client app is connecting to server with PostgreSQL network protocol, but the client uses JDBC driver for this

Marin Orlić

I'm not sure ANTLR was a requirement, more of a design choice

Marin Orlić

This will need to explained, mention how will the requirement be tested (for instance, for PostgreSQL req, you can say that a standard JDBC driver for pgsql will be used, to test the server-side implementation of the protocol)

Functional Requirements 2/2

DBMS Semantic layer• Query validation;

• Simple SELECT statements;

• Inner join on multiple relations.

• Querying (SPARQL) remote and local data sources;

• Retrieve source meta-data;

• Extandable with heterogeneous, distributed sources.

**

Non-Functional Requirements

Usability

Reliability

Performance

Marin Orlić

How will you verify if NF reqs are met?

**

Component Architecture

Marin Orlić

Only box titles were readable last time in ZG. Can you put just the figure on the slide?


Can we not put the FER-Polimi-MDH signature below the slide?

Step 1. Create DB schema definition.

Data Flow 1/2


thats what this DFD is about

Marin Orlić

Isn't manager app responsible for creation of DB schema definition?


it is

Marin Orlić

Put step 1. in the title with a shorter description?

Step 2. Deliver the required data to the Client App.

Data Flow 2/2

Marin Orlić

nice figures, though :)

Marin Orlić

This might be unreadable too... perhaps split into two figures (steps 1-4, steps 5-8)?

**

•DriverJDBC 4.1 JSR

•open source RDB driver specification

PostgreSQL protocol•protocol for server-client communication

ANTLR•SQL parse, syntax check and validation

•Semantic layerJena API

•Java RDF API for querying semantic data

SPARQL•query language for semantic data sources

Technologies and tools


Some label pictures here

Marin Orlić

On this and next slide - add explanations, what each of these tech do? you got a comment for that on the first presentation

•Manager back/front endJersey

•API for building RESTful web-services

javascript•front-end code

backbone.js•javascript structuring framework

require.js, underscore.js•dependency injection & utilities

HTML5, CSS•visuals

Technologies and tools


Some label pictures here

Marin Orlić

If there's no explanation why these technologies are used, there's not much value in last two slides

Agile Software Development

Week iterations(7)Steps:1. Detailed week plan2. Identify problems3. Design4. Implementation5. Testing6. Integration

Development methodology

Marin Orlić

Do you have proof of the steps for the first two iterations? If not, why :)

First requirements, creating teams, separating jobs

MILESTONE /DELIVERABLE 1

MILESTONE/DELIVERABLE 2

Milestones

David Riobó

2nd one, in progress

David Riobó

1st one, all parts integrated communicating with mocked data

Marin Orlić

What will you say here?

Marin Orlić

For each milestone, you need to list what should be done - what juraj said last time, if you can't measure the progress at a milestone, there's no point

Milestone 1

Milestone 1

•Communication Client/Server•Definition of interfaces•Basic functionalities for administration

•Basic parsing functionality•Application works with ad hoc data•Slightly behind schedule

Milestone 2

• Integration of all layers•Data types support•All parsing functionality•All functional requirements are fully implemented

•Application works with real world data

Milestone 2

•Weekly documents•Deriverable documents•Minutes of Meeting•Weekly summary•Never delete documents!

Documentation

Marin Orlić

Documentation policy? Can you mention that gdocs is used, and deliverables are pushed to fer web?

Activity plan 1

Marin Orlić

somewhere :) this pres. was meant to be about project status and revised plan, so you should talk about that also

David Riobó

Do we have to put that here?

Marin Orlić

What has changed in the project plan? for instance, for the first iteration you should have more details now (it's finished), and an overall idea what will be done in the second iteration

Activity plan 2

Activity plan 3

•Divergent project tracks•Project feasibility•Team members leave the project•Communication issues•Integration problems•Lack of experience•Team members miss meetings•Language misunderstanding

Project Risks

Marin Orlić

Mitigation?

First iteration results

● Front-end, DBMS and semantic assignments finished as supposed

● Problems with the type 4 JDBC client-server connection.

Progress

Marin Orlić

Milestone? what was finished/delivered? is project on track?

Actions after first iteration/Second iteration

• Redistribution of work to finish the server-client part on the second iteration.• Connection of all parts.

• Test of functionality with mocked data.

Progress

Thank you for your attention! Questions?


Some question pic here

Marin Orlić

Project status is missing, how many hours have been used, where are you according to the plan (progress), what is planned for the next iteration, what are you working on now, how is the work distributed, what are the problems, did you have to make or change any architectural decisions? how did you cope with a loss of one team member? what about the problems you had which were discussed last time, did you manage to overcome them? what did you do to overcome them, how will you avoid to have it happening again?i expect you'll get a lot of questions like these, it's better to talk about it openly :)

Marin Orlić

There was also a change in project management, you need to mention that too
